  Distance Dependence of Photoinduced Electron Transfer in Metalloporphyrin Dimers

  摘要：

  To study the dynamics and mechanism of intramolecular photoinduced electron transfer (PET) reactions, a series of (Zn-II-Fe-III), meso-tetraarylmetalloporphyrin dimers were synthesized and the kinetics of their PET reactivity was measured. Molecular building blocks were prepared by selective nucleophilic aromatic substitution of a para fluorine on tetraarylporphyrins containing a single pentafluorophenyl group. This synthetic approach allows a wide variety of systematic modifications such as type and length of spacer, metal center, and redox-potential difference between donor and acceptor. The edge-to-edge distance between the two porphyrins varies from 14.4 to 27.3 Angstrom. Into a symmetric dimer, with two identical porphyrins covalently linked by a rigid partly saturated bridge, one zinc(II) and one iron(III) can be inserted. From measurements of fluorescence lifetimes the rate constants for PET from the electronically excited state of the zinc porphyrin to the bis(imidazole)iron porphyrin cation were evaluated. The electron-transfer rate decreases by a factor of only 165 when the distance increases by 13 Angstrom. This small decrease is indicative of a surprisingly weak attenuation of the electronic coupling with distance.

  卤代锰卟啉在均相溶液中催化碘烷基苯和过氧化氢氧化烷烃和烯烃，并与二氧化硅共价键合

  摘要：

  锰（III）5-（五氟苯基）-10,15,20-三（2,6-二氯苯基）卟啉，Mn（PFTDCPP）和锰（II）2,3,7,8,12,13,17， 18-八氯-5-（五氟苯基）-10,15-20-三（2,6-二氯苯基）卟啉，Mn（PFTDCCl 8PP）已合成，并用作溶液中与共价键合至氨基丙基化二氧化硅的碘基苯和过氧化氢在烃类氧化中的催化剂。前者在碘烷基苯环烯烃的环氧化反应中显示出更高的效率，而高氯锰卟啉在这种氧化剂对烷烃的羟基化反应中更有效。负载的锰（III）卟啉具有与其均相类似物相同的活性。以过氧化氢为氧供体，Mn（PFTDCPP）在咪唑存在下是一种稳定有效的催化剂。高氯酸盐类似物是这种氧化剂的不良催化剂。卟啉环上的另外八个氯原子稳定了Mn（II），不利于活性物种Mn V = O的形成。
